To. all who/m it may concern :l

. 113e it known thatpwe, AXEL WYMAN Ea'roN, andJoHN Z. Gontran, citizens 'of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful Improvement in Pinion-Housings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in whichA Figure l is an en d elevation artly in section of a pinion housing for job ing mill, constructed in accordancewith our invention. Eig.. 2 i's apfront. elevation of the same partly broken away. Fig. 3 is a. section on the irregular line Ill-III of Fig. l. Fig.. 4 is a broken detail showing a partial top plan of the housing with the spacer block in place. Fig. 5 is aside elevation ofV the bearing shell partly in section. Fig. 6 is a perspective view of the spacer block. Fig. 7 is an end elevation showing the invention applied to a4 pinion housing for a plate mill, and Figs. 8 and 9 are perspective views of the spacing blocks employed in Fig. 7.

Our invention relates to pinion housings and is designed to give the strength and rigidity of an integral housing, while, at the same time, affording advantages of a divided housing.

In the drawings, referring to the form of Figs. 1 to 6 inclusive, 2 represents the housing `havin the usual cap 3 secured by through-bolts 4. The inner vertical faces of the housing are cut outwardly, as shown at 5, and these cut back faces are Vpreferably concave in form, as shown in Figs. 3 and 4. The housing and the cap are provided with semi-cylindrical recesses to receive the bearing shells 6 for the pinion necks, these shells being preferably bushed or lined with babbitt 7, as shown. The shells are provided with fianges 8 which project over the inner and outer faces of the housing and cap and prevent endwise movement.

Between the bearing shells at each end lof the housing we employ a spacing block 9, shown in Fig. 6, having outer convex faces l0 which fit the concave faces of the window recess, the top and bottom of this spacing block havin semi-cylindrical recesses to fit the other ha f of the bearing shells.

In assembling the pinions in the housing,

H. HEnANnEn,

the shells are slid on theneckof the lower pinion which isdroppedt into place. The spacing block 9 is then slid down into posi.- tion and the upper oinion with its bearing shells in place is then dropped in. The, housing cap is then fitted on and the' through-bolts drawn up. The spacing block holds the upper half vof the lower bearing shell and the lower half 'of the upper' bearing shell in position and is itself held bythe co-actin concave and convex facesibetiveen it and t e housing.

lIn Figs... 7 to 9, inclusive, we :show the invention as applied to a husingcontaining three pinions. In thisform, the cap con-1 tains one semi-cylindrical recess lfor the upper half of one shell 6 and at the bottom of the window the housing. 2.a has a lcorresponding recess for the third shell 6*. The third shell is held withimsemi-cylindrical mating recesses in the other portion of the spacing block 9a which is made in. two halves split to receive the third pinion shell. In this case again the vertical faces of the window and the co'a'cting faces of the bearing block are made Ofinteritting concave and convex form, and the parts are assembled in the saine general way as before. In this split form of spacing block, a key 11 may be driven into the matingrecesses 11 between the halves to more .effectively retain them in alinement.

In all the forms shown, the shells 6 o r 6 are prevented from turning by providing the outer flanges of the shells with flattened surfaces 12, which, in the form of Figs. 1 to G, coact with each other, and in the form of Figs. 7 to 9 coact with flat-faced projections 13 on the'spacing block to prevent rotation. Those shells maybe made either as a complete integral cylinder or may be made in halves or a plurality of parts. In Fi 5, we have shown a complete shell 6, whi e in Fig. 7, we show the shells 6 made in two semi-cylindrical halves.

The advantages of our invention result from the use of an integral housing while, at the same time, the advantages of a split housing are obtained. The interfitting faces of the bearingr block and window may be varied to any desirable interfitting form, the spacer may be changed in form and size, and other changes may be made without departing from our invention.

Byl the words spacingblock 'in the claims, we intend to cover the block whether made in one part orv in s. variety 'of4 parts.

We claim:

1. A pinion housing having a recessed window and a lower semicylindrical shell receiving recess, a removable spacing block within the window 'and having a plurality of shell receiving recesses', a. cap having a corresponding shell receiving recess formed therein, a shell for receiving the pinion necks in one of the recesses in thespacing block land the` recess inthe housing, a similar shell in another recess inthe spacingvblock and the cap, and bolts for securing the cap in position for retaining the shells and spacing block in position Within thev Window; substantially as described. I

2. A pinion housing having its window recessed at the side and a shell receiving recess in vthe bottom thereof, seats at the lower ends of the side recesses, a removable spacing block seated within theside recesses and resting on saidseats, said spacing block having upper and lower recesses', a caphaving a shell receiving recess, a shellfor a pinion neck seated within the recess in the bottom 'of the spacing block and the Window of the housing, a similar shell seated within the-recessin the upper dportieri of the spacing block and cap, an securin bolts for securing the ca 1n position'on t e housing to retaln the ls ells and spacing blocks in position; substantially as described.

3. Av pinion housing having a recessed window and a lower semi-cylindrical shell receiving recess, avrernovable spacing-block within the window and having a plurality of shell receiving recesses, a cap having a corresponding shell receiving recess formed therein, a shell for receiving the 4pinion necks in one of the recesses in the spacing block'and the recess in the h'olsing, a similar shell lin another recess'in the spacing block and the cap, bolts` for securing the cap in position for retainingA the shells and spacin block in position wlthin the window, an means on the shells for preventing rotation of the shells relative to, thel housing; substantially as described. A

Intestimony whereof, we have hereunto set our hands. i z
